近些年超声心动图检查发现,部分因心力衰竭而就诊患者心室腔内存在粗大突起的肌小梁和深陷隐窝,因而将其诊断为心肌致密化不全(noncom-paction of ventricular myocardium,NVM)性心肌病。由于这些患者存在心脏扩大征象,临床症状与扩张型心肌病(DCM)相似,如何早期识别NVM,应当引 In recent years, echocardiography has found that, in part, due to heart failure, patients are found to have grossly protruded trabecular and deep crypts in the ventricular cavity, thus diagnosing their noncompaction of ventricular myocardium (NVM) Cardiomyopathy. Since these patients have signs of enlargement of the heart and their clinical symptoms are similar to those of DCM, how to identify NVM early should be
